11 claims. (drama-264) My invention pertains to dump carsof the-typehaving .the body ofthe -car tiltably mounted so as .to provide forselective discharge of the lading at a side of the car, and moreparticularly to a vmechanism for manually controlling selective tilting.of the car body.

ATilting body dump cars fall into two general classes, i. e. thosemanually tilted and those tilted through the use of a uid pressuremedium or an equivalent mechanical force. My invention per- .tains tothe manually operated tilting body dump i cars; Usually this class ofdump car is limit-ed in scopeto relatively small capacities because ofthe manual eiort involved in moving the loaded body from normal lading'receiving and transporting position into lading dumping or dischargingposi- As the lading capacity of these cars is tilting the bodyproportionally increased and v`it has beenV heretofore necessary toemploy two or more workmen in tilting the car body of or .more -cubicfeet capacity. Various types of bea-r- .ings have been provided uponwhich the carubody is supported for dumping, in order to reduce the 1manual effort involved intilting thebody out of normal position andreturning same to thatiposi- Vtion. It was early recognized that to useafrocker bearing for supporting-the tilting body, in place vof spacedbearings, would reduce the manual effort involved in tilting the Ycarbody but would in turn introduce the problem ofA maintaining the carbody in stable equilibrium on the"` underframe.

` Latching means for retaining the rocker bear- Ving mounted body Yinstable equilibrium were de-.v`

veloped early in the art and where the rbody was mounted to tiltselectively abouteither `side of the underirame, diii'iculties wereencountered by way of having the bodies tilt tothe Wrong side of theunderframe when the latches were released because of eccentricity in theloading of the lad- Ving within the car body or because of concentratedloading such as encountered where large stones or similarlyconcentratedweight formed a part of the lading. Likewise, asv thecapacity of the body was increased the need for `,Irlfftilllal-lyoperated dumping mechanisms arose and inthe larger type bodies tWo ormore dumpingmechanisms began to be employed thereby necessitating aplurality of workmen, often twoor more 1 to one dumping mechanism, totilt thefbody to discharging position and to return the body tonermalposition. Here again the problem'of selective release of the latchingmeehanismtopermit tilting ofthe body was encountered. e

, my invention, as hereinafter set forth, I not Y.only provide asolution for .the di'iculties encountered in .the `body supportingbearings and dthe latching mechanism but also a new and novel Iorm ,oimanually operated dumping mechanism, vallor lwhich are so .assembled andcoordinated :on .the 'car as .to permit cars of relatively largecapacity to `be .tilted and righted by a single workman .or in the caseof the use of vplural mechanism, a single operator ateach mechanism.

-flfhe .car hereinafter to be described and as -disclosed inthe drawingshas a lading capacity of i108 cu. ft.` vof ylading which weighsapproximately 5,060# vObviously the foregoing iigures do not .place alimit `on Athe-lading capacity of vbody 'for ja carlonwhich my inventioncan Abe' used since .any person skilled in the kart after an examina-,.tion, of Vthe disclosuresherein can readily modify the mechanismwithin reasonable limits for any k,desired purpose.

One object of my invention is to provide a v.tiltable `car body of thecharacter described with a supporting bearing of a designproviding aprog'res'sivelowering ofthe height of the center of Ygravity ofa-'loaded car body asthe body moves from' normal to tilted position.

Another object of my invention is to provide abearing of the characterdescribed which mainxtains `the position of the center of gravity oftheYempty body-in substantially a horizontal plane as the car .body movesfrom dumping to normal positionthereby facilitating the return vof thebody from dump to normal position witli'a minimum expenditure of manualeffort.

Another `object of my invention is to provideA `alatching mechanismwhich will maintain the bodyi-n stable equilibrium whilst thebody is innormal `orloading and vtransporting position and Lwill also permitselective release 'of thelatching vmeans at one side of the body so asto permit tilt- Vingv ofthe body to dischargel the lading to theopposite side' 'of the car and at the' same time :positively preventundesired harmful tilting of the body in the opposite direction duringany and all positions of the body in ymoving from n or- .mal tofullydumped position.`

' A liurtherobject of myinvention is to provide a manually operated andcontrolled mechanism vvfor moving the body from normal to dump positionand for returning the body from dump to Y normal' 'p' sition.v`

'A l'still further object ofmy invention is to so vcoordinate thelatchingand dumping mechanism sothat when the latching mechanism isselec- Ntive'ly released for tilting the body,the dumping tion.

dumping mechanism forming part of the present invention; Fig. 3 shows infull lines an end elevation of the car when in normal position. similarto that shown in Fig. 1 of the drawingsbut having the latchingmechanismv at one'sidebf" the car released to permit the car to betilted towards the opposite side ofthe underframe."

This latter figure also illustrates therposition of the dumpingmechanism when moved to operative position and prior to any dumpingmovement of. the ladying body. On Fig. 3 and in dot and dash lines 'areshown three positionsof the tilting body-as it moves progressively fromnormal to tilted position and is returned; the first tilted position ofthe body illustrates the relationship between the tilting body and thedumping mechanism at the point during the tilting of the body wherethedumping mechanism ceases to be effective in tilting the body; thelowermost tilted position of the body` illustrates the relative positionbetween the body, the underframe,

and the body return portion ofthe tilting mechanism when the body is inextreme dump position;

and the intermediate tilted position .of thebody illustrates therelativepositions between the body and the body tilting vmechanism atthe point Vwhere the body return portion of the. body tilt- Y ingmechanism ceases to exert-any effort upon the body in moving from dumpto-normal 'posi-.

Referring now to the drawings wherein like referencecharacters refer tolike parts: A conventional form of car underframe is'illu'stratedcomprising. spaced side sills "I which are connected by suitable meanssuch as end' plates 2 and 3. This underframe is supported on anysuitable wheel and axle assembly such as 4 connected to the underframeby means ofA bearings the reference character 6, 'may be made forattachment of a coupling means should it be desired to operate thesecarsin train. Adjacent opposite ends of the underframe' are provided I vbody bearing supporting members such as 1 disposed transversely of theunderframe and securedthereto. The form of the members 1 lasillustrated, is a commercially rolled channel having both anges disposedtoward the adjacent end of the car and the web of the channel disposedin a vertical position. A suitably'shaped car body 8 of the desiredcapacity is-disposed above the underframe between the'- members 1 andsupported on the latter by means of rockerV bearings S mounted on eachend of the car body and in engagement with the top flange of theadjacent member 1. These rocker bearings 9 include a rigid portion II)having the outer face of the periphery thereof formed on a ysemioirclestruck from a point slightly above the center of gravity of the emptylading body 8. It is this t portion I8 of the bearing 9 which engagesthe upper Vflange ofthe adjacent transverse memrvb'e'rfl `between themembers 42 thereon and is At one or both ends of the under- "l framesuitable provisions, such as indicated by v the body V8.

provided with suitable projections II engaging in suitable apertures inthe upper flange of the member 1 to guide and maintain the members 9 and1 in operative relationship as the body tilts in dumping. Intermediatethe ends of the member Ill and projecting downwardly therefrom tooverlap the member 1 is a member I2 secured to the member I to restrictrelative movement between the member I0 and the member 1 longitudinallyof the car when the body is in normal upright position. The member I0 ispreferably secured to a base I3 of the bearing 9 as by welding andfurther suitably braced by ribs I4 and I5. Disposed across the member 1between the upper and lower flanges thereof is a member IS and a memberI1, the members I6 and I1 forming a pocket within which the member I2moves,v and at the same time provides a verticalsupport for the member'I to resist distortion from the weight of the lading within Adjacentopposite 'ends Vof each member lare latch 'members' I8 each having oneend pivotally mounted on'a pin lsup'portedr by a bracket 28 securedtothe member 1. The oppositeend of each latchV I8, which is' disposedabove the member 1 and preferably inwardly 'of the pin I 9, has Aa.suitably shaped portion adapted to jengage a pinV 2I which is securedtothe car body and preferably at the 'end of the portion I v@ofthebearing 9. It will' beobvious from an inspection*` of Fig. 1 ofthevdrawings that when the latches- I8 at opposite ends'of the member 1 havetheir upper portions engaging the pinsv 2| adjacent each vside ofVthecar body 8, the'body will be maintained in upright stableequilibrium and cannot be tilted' toward either' side 'of the car until'after one of -the latches I8 lhave been moved torelease position, asillustrated in Fig. '3. The mechanism provided for tilting the'car bodycomprises a lever 22 anda latch` 23, A'both pivotally mounted on-thelatch I8 bymeans of'a common pin 24.

This'latch 23 depends' below the pin 24 and has an aperture 25 extendinglongitudinally thereof and terminating in anA offset portion 26. Mountedonthe adjacent member 1 is a bracket 21 extending upwardly from themember 1 and adjacent the latch V23. A suitable pin 28 is secured on thebracket 21y and ex- Y tendsinto the aperture 25 of the latch 23. Thispin 2 8 isdisposed adjacent the uppermost portion of-thev aperture 25 inthe latch- 23'when the .bodyf latch I8 isengaged with the pin 2I of therocker bearing 9, as indicated in Fig. 1 of the drawings. The lever 22,which lisjlikewise mountedA on the latch I8 by means of the pin 24,

has a top portion 29 extending upwardly Vand out- Wardly from the'pin-24 to a point toward the adjacent side of the body 8` when thel latteris in normalposition. The major portion of the lever 22. depends belowthe pin 24 and terminatesin a handle portion 30, the distance of thehandle portion 30of the latch from the pinv 24' being determined vby theamount of effort necessary to tilt the car body. Thehandle 30 ispreferably disposed outwardly of the side of the car underframe topreventinterference therewith, as illustrated in Fig. 1 of the drawings.A pin 40 mounted on latch..I8 above pin I9 engages-lever 22 to limitinwardmovement vof lever 22, as illustrated in Figs..1 and 3. Y

-Theputermost topface of the portion 29 of the leverl2'2. is preferablycurvedy and shaped' so that the outermost end portion vof the-head29-wil1 "lie below-a *bearing bar 3|, mounted on vthe side of the carbody by any suitable means such as the 1 24 extends.

' bracket .32..asshown in Fig. V1 of. the vdrawings andV when the lever22 is ymoved to .operative position,

-as shown rin Fig. 3 .of the drawings, 'the head 29 will move freelybeneath .the :bar 3l. The lever .22 in the form .shown in Figs. 1 and 2is provided with a .suitable .offset 33 and brace 34 to clear'the headof pin 19. It 'will be obvious that this is merely a detail ofconstructionfnecessitated by the relative positions of the latch I8,lever'22,

- and pin I9. In :order tto retain the latch .23 in position on .the pin2.4 in the :latch lraIfhave pro- 'vided .suitable means such as themember 35 which is rigidly secured tothe lever 22 and has an aperture inone end thereof into which the pin threaded .and .a bolt 36 mounted .on.the .threaded portion of the pin 2d secures the latches .I8 and 23 andthe lever 22 inxed pivotal relationship through the pin 24.

The number of tiltingmechanisms provided on each .car will vary with thelading .capaci-ty of the car body and the manner of using .the cars.Where :the Vcapacity is very large and the body is vtilted'selectivelyto either side .ofthe underframe, four tilting mechanisms may beprovided, one on each latch IB as shown on Fig. 1 of the drawings.

. In the case of smaller .cars but two tilting mechanisms may be used.and disposed on diagonally opposite ends of the .car body. Obviously,inthe 4case of car bodies tilting in one direction only, the

. tilting mechanisms will be mounted at but `one side ofthe car and atone .or .both ends as found desirable.

WVhilst I prefer fin the larger sized cars to provide a lever Y22 oneach latch 18,1 have found -that even in the cases'where the body tiltsselec- .tively about opposite sides of the car underframe I need toprovide but fone body righting mechanism at each end of the car and tomount these body righting mechanisms at diagonally opposite ends of thecar. This is done because but one bodyrighting mechanism is Ausuallynecessary to right the body by reason of the bearing support used andalso Vwhen mounting the righting-mechanisms at opposite ends of the:body interference t between `righting mechanisms is avoided. vThe.righting mechanism is preferably mounted on one of the pins I9, such as19a, and is preferably disposed behind the member 1, as indicated inFig. 2 .of the drawings. This righting mechanism comprises a lever3'1having its upper portion suitably apertured and mounted on the pin I9a.This lever 31 depends from the pin I9it and extends below the lower edge`of Ythe member 1 for a vpurpose hereinafter described. Intermediatethe4 Aends of the lever 31 is rigidly fastened onefend -of a lever 38kwhich extends transversely of 4the Y car underframe and when the bodyis in normal position rests upon the underframe at the side thereofopposite the lever 31. The free end of the lever 38 terminates in asuitable handle por- The normal ,positions of the levers 31 and 38 areasillustrated in Fig. .1 of the drawings.

I When, however, the'bodyis in fully tilted `position, as shown in Fig.3 by dot and dash lines.

marked with the reference-character 8a, fthe bar 3l engages hthe flever31 causingzit to rotate inwardly on its pin .I9a into ytheposition-marked 311a thereby causing the vrlever 8 andits handle 39 tomove into theposition indicated by dot and :dash lines on Fig. 3andmarked with reference characters 38a and 39e.

In this position .of thelatches |18 the car dumping mechanism isrendered inoperative for it will be .obvious that if .the operatorgrasps the handle portion 30 .ofthe lever .22 and rotates the lever .22upwardly, the portion 29a of .thehead 29 of the lever .22 will .pass:beneath the pin ISI. wise of importance that when the levers .22 haveItheir headfiportions 2.9 disposed in the position .illustrated'in Fig.1 `of the -drawings the bar 3| outof engagement with 'theend portion29a.of

'-left side lof the runder-frame as illustrated in Fig. 3 of thedrawings, the operator grasps the pin `lill in @the head fof the ,latchI8 at the right hand side of the under-frame and rotates the latch I3lupwardly and outwardly :towards the right side of the car A'body into'the -position illustrated in `Fig. 3 -of lthe drawings.

tratedonthe rightsideof Fig.A 3 of the drawings. Under normal conditions`the latch 23 'will `rotate downwardly `by .gravity to move apertureolfset 2B into engagement with the pin 28Qto retain the latches -I8 and23 .and the lever 22 in the Ypositionsv as shown in Fig. J3 of thedrawings. Iff this gravitational movement does not occur Yi1; will be 4avsimple matter forthe operator to mannually -move the latch 23 into'-the latter V--As illustrated Vin Fig. 3 of ythe drawings the latch YI8is new `locked in 4its elevated position by means of -theilatc-h 2 3 andpin 28 and, likethe bar 3l fastened -at the right side ofthe car body.Ifduring ythis described movement of the latchVIgS there should be anyinterference between the head 29 of the lever '22- and the bar the lever212 to permitimovement thereof beneath fUnder normal -circumstances thelever 22 will normally move by gravity so as to depress lthe head' '29of Ythe 'lever 22, but if this vdoes not-occur engagement with pin 3Iwill produce-the desired results. f

From an inspection o'Fig. 3 of the drawings itwill Inow be obvious thatthe car is Afree to -be vtilted toward the -left side of the underframe,4'asviewed in Fig. The operator, grasping hanlillustrates the 'pointduring-*the tilting of the body where thelbar 13| fmovesout'ofengagement with :head 2:94 of the lever 22 withi-the continued It islike- `During this rotation -ofjthe said latch I8, the latch 23 pivotingon l,the pin '-254 secured-on the latch I8 moves upwardly and outwardlyuntil thev pin 28 approaches ltheend-of -the aperture 25 in the latch.23 and thereafter -moves v'into engagement with Vtheoffset portion =26of the aperture, as illustilting of the car body.v :During'movement' ofthe body from normal position into '.that'marked bythe Yreferencechara'cter 8b the body has acquired suiiicient.momentum to carryitionover into fully dumpedposition, as illustrated in dot and dash lines onFig-:3 and marked' with'the reference character 8a. f

It will be recalled, as previously stated, that the portion l of thebearing Slis'formed on a semicircle struck from a point slightlybelowthe center of .gravity of the empty body, which is indicated by thereference' character A' on Fig. 3'of the drawing. Obviously, therefore,the portion I8 of the bearing 9 moving along the top face of' the member'l will tend'to carryfthe l center of gravity of the empty'body'along asubstantially straight line until the point A reaches the pointC, whichis Athe position of the center of gravity of theA empty body when thevbody is in fully ,tiltedpositiom It'will likewise be obvious that thecenterof gravity of the loaded body will be above the point A and willmove outwardly and downwardly to the point C along apath marked by dotand dash lines connecting points B and C as the lading progressivelypasses out of the bodyduring movement of the body fromY normal positionto` fully dumped position as indicated in dot and dash lines and markedwith the reference character 8a. From a comparison of the lines AC andBC on Fig. 3 it will be apparent that any-,momentum built up in the bodymoving from the normal position to dumped position will be suicient tocarry the body from the position marked 8b to the position marked 8awithout any assistance from the leverr22. f j

Referring n ow to the position of the fully tilted body, indicated bythe reference character 8a on Fig. 3 of the drawings, it will beobserved that in-.this position of the body the bar 3| has moved thelever 31 intoV the position marked 318' and moved the lever 38-39 intothe position marked 39a in Fig. 3 of the drawings. Therefore, when theoperator is ready to right the body he grasps the handle portion 39'iLof the lever 38, rotating it downwardly upon the pin I9, to move thelever v3l outwardly until the lever 38 engagesy the underframe, which isthe position of the lever 38 indicated by full lines on Fig. 3 of thedrawings. During this movement of the levers 31 and 38, the lever 3l inengagement with the pin 3| has moved the body into the positionindicated by dot and dash lines on Fig. 3 of the drawings and markedwith the reference character 8. It will be obvious that on account ofthe previously described construction of the bearing 9 the momentumbuilt up in the body during its passage from position marked 8a tothat-marked 8 will be sufficient to cause the body to continue until itreaches normal position and, if for any reason the body should notcontinue on to normal position, a very slight force exerted by theoperator on the body'will cause it to complete itsmovement to normalposition,rwhich is illustrated by full lines in Fig 3 of the drawings.

When the body reaches the position as illustrated in full lines on Fig.3 of the drawings, the

pin 2l at the left sidejof. the gearing 9 engages the adjacent latch I8and prevents further lrotation of the body. At this point the operatorthen grasps latch 23 at the right side of the body, rotating itVupwardly until pin 28 moves into engagement with aperture in latch'23,and there- `after the latch I8 at the vrightside of the body will movedownwardly by. gravity and the weight rof lever..22 and latch 213, untilthis latter latch I8 engages the pin 2|, thereby'locking the body in'normal upright position.

y Obviously where' it is desired to discharge ladexcept asmade'necessary bythe scope of the appended claims.
